"On Oct. 12, the U.S. Federal Reserve Board of Governors agreed to extend Federal Reserve contingency lines of credit to two {British} banks--$10 billion to the Royal Bank of Scotland (RBS), and $20 billion to Barclays, two of Britain's Big 4 banks. The Federal Reserve would open these $30 billion facilities to the two banks, should the banks, in turn, need them to extend credit to their clients "in need of short-term liquidity to finance their holdings of securities and certain other assets," the Federal Reserve said in a letter to the banks."
